Honorable mention though, Our group solo tanked (me) stone guard for 20% of its health last night and I spammed AOE against all three dogs while we healed through the explosions. They were timed pretty well, with 1 dog hitting 100% while another at ~60% and the last at ~30%. With no dog getting the 90% reduction, aoe spamming looks like it could be viable with higher average ilevel across a group.

ty for the reply my bad i forgot to mention this is for ret and heroic

Honestly this fight can be done multiple ways, I've seen 2 targets being dps'd and I've seen single target dps only. So it's more based on your strategy you can't really just say do this or do that because we don't know what strategy your raid is employing.
